[Hibernate] saving to pgsql

[cheeser <hib...@ch...>]

I'm having troubles getting my objects to persist.  In my pgsql.err, i ge=
t=20
error messages about "unexpected EOF on client connection."  Has anyone s=
een=20
this?  I create the bean and call session.save() with it.  When I'm done =
with=20
the session, I call flush() and close() (trying to force it) and nothing =
gets=20
saved.  Here's part of my hibernate.xml:

=09<class name=3D"org.cheeseronline.antfarm.system.CommentBean"
=09=09table=3D"CommentTable" discriminator-value=3D"Comment">

=09=09<id name=3D"PrimaryKey">
=09=09=09<generator class=3D"cirrus.hibernate.id.HiLoGenerator">
=09=09=09=09<param>uid_table</param>
=09=09=09=09<param>next_hi_value_column</param>
=09=09=09</generator>
=09=09</id>
=09=09<discriminator column=3D"subclass" type=3D"string"/>
=09=09<property name=3D"Text" type=3D"string" column=3D"Value"/>
=09=09<property name=3D"DateEntered" type=3D"date"/>
=09</class>

There are other classes in there, but the code is generated so it all loo=
ks=20
the same.  Can anyone see what I'm doing wrong?

postgres closes connection if it detects error in protocol, something like
this can produce this error:
char c = '\u0000';
String query = "select " + c;
statement.execute(query);// error not detected by driver, server closes
connection;
I am not sure about all driver versions, but it must be possible to
reproduce on most of them.
